Preparation and Performance of Bio-Adhesive Based on Acorn Starch Graft Glycidyl Methacrylate

Abstract

For improving the performance of acorn starch (AS) based bio-adhesive, AS graft glycidyl methacrylate (AS-g-GMA) adhesive was prepared in this paper. The properties of the AS-g-GMA adhesive were studied by Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) measurement. The bonding strength of the plywood bonded by AS-g-GMA adhesive was measured according to Chinese National Standards methods to evaluate its water resistant. FTIR results indicated that GMA was grafted on the AS successfully. The bonding strength of the plywood bonded by AS-g-GMA adhesive showed lower curing temperature, better bonding strength, and water resistance comparing with that of control. The water resistant could reach type II grade (63°C water bath 3h) plywood requirement when the glycidyl methacrylate adding amount was 6% based on AS.

Starch Grafted Water Resistant Polyvinyl Acetate-Based Wood Adhesive: A Review

“…The results showed that the properties of wood adhesive could improve dramatically by using two co-monomers [84]. For improving the performance of a cornstarch-based biobased adhesive, corn starch graft glycidyl methacrylate adhesive was prepared [85]. Graft copolymerization, which has improved the structural, physical, chemical and mechanical properties of adhesive, is considered to be one of the most effective methods employed to modify many different properties of starch-based polymers.…”

Starch-Based Adhesives for Wood/Wood Composite Bonding: Review

“…Adhesives made of conventional materials when compared with biopolymer-based adhesives are usually too weak for practical use [100], so the structural strength of starch-based adhesive should be strengthened to achieve high performance as a wood adhesive. For improving the performance of a corn starch based bio-adhesive, corn starch graft glycidyl methacrylate (AS-g-GMA) adhesive was prepared [101].…”
